We use as an example an instance of the one-species
CRN (REF ) drawn
from [1]}, [2]}, with
parameters \({\bar{k}}_1 = 1\) , \(k_1 = 14\) , \(\epsilon = 36\) , \(k_2 = 49\) .
At these parameters the mean-field rate
equation (REF ) has stable zeros at \(n / n_C ={\bar{x}}_1 = 1\)  and \({\bar{x}}_3 = 9\) , and a saddle-point zero
\({\bar{x}}_2 = 4\) .
